Bad TPS?

[ravage]

Having some throttle response issues. Issue is there is zero throttle response. Linkage is all intact and the throttle plates inside the throttle body are moving, yet there is zero response. Engine idles fine and there are no problems starting. Recently changed over to an Accufab throttle body, but everything has been fine until now. Any thoughts?

With key on, engine off: datalog the TPS and push the pedal in and out. See what the TPS signal looks like. Or you could do it with a multimeter, but it will probably be easier to see while data logging.
